Is a PCIe Gen5 SSD worth it over a Gen4 drive?

For most gamers and general users, no. Across the reviewers and specialist communities we read, the consensus is that Gen5 drives like the Samsung 9100 PRO deliver enormous sequential numbers but only marginal real-world gains for game loads, while costing roughly twice the price per terabyte and running hotter. Gen5 makes the most sense for heavy content-creation, AI workflows, or 'best of everything' builds. Several community threads also flag Gen5 drives underperforming their advertised speeds in real systems.
